Everything was ok but it took like a week to receive the order when it appeared as completed in the status. Maybe more reliable information on the delivery process would be appreciated.

However, the key signs that your filters need replacing include:– An increase in noise from the HRV– A reduction in the amount of air being supplied or extractedSmart HRVs with an electronic control panel and display screen show the volume of air supplied and extracted per hour.For example, if a Zehnder ComfoAir Q350 HRV in a 140m² home operates at an optimal rate of 190m³ per hour but drops to 150–170m³, the filters should be replaced.What is the difference between G4, M5, F7, etc. class filters?Filter class refers to the size and amount of particles a filter can trap. The higher the classification, the more effectively the filter removes particles from the air.
For incoming outdoor air, it’s generally recommended to use higher-class filters. However, we always suggest following the manufacturer’s guidance and using the specific filter sets outlined in your unit’s eco-commissioning documentation.
